Submitting Insect & Spider Specimens (no charge for this service)

  • We may be able to identify your insect or spider from one or more quality photos: Photo Submission Form (no cost)
  • We also accept insect (and spider) specimens by mail or drop-off to the address below.
  • Important Note: Please do not send us floor sweepings, vacuum cleaner contents or specimens from the body (although ticks, suspected nits and lice will be accepted). Due to potential health risks to our diagnosticians, we cannot accept bodily fluids or other human debris. We are happy to work with a physician to identify any arthropod pest, but submissions of that nature must come directly from a physician.

Please print and fill out the following form to include with any physical sample(s).  If you are without a working printer, we ask that you write down the information for us on a sheet of paper to accompany the sample(s) — Thank You!

How to properly submit a specimen for identification:

  • All insects (excluding butterflies and moths) should be placed in a small leak-proof container with just enough rubbing alcohol to cover specimen for preservation.
  • Butterflies and moths should be packed in tissue or cotton for best possible preservation.
  • You can mail or drop off specimens at your local County Extension Office or at the Pest Management Unit’s Insect ID Lab.
  • Important Note: Please do not submit floor sweepings, vacuum cleaner contents or specimens from the body (although ticks, suspected nits and lice will be accepted).
